i havent found it, unless the item button is it. I got hammer, coins ladder club key, and handcuff key, as you can tell i am early in the puzzle. i see all the points in the game but not finding the triggers or a certain piece..
Have you done the movement puzzle (green square at entrance and notebook?) What about checking the table on the left from the entrance? Did you find/use both clues from the notebook?
There will be a Days 14-16 free version released at some point, though I'm prepping the game for a Steam release, so I'm still nailing down all the details.
